CANAL AND THE MODE OF NAVIGATING THE SAME.

SPECIFICATION forming part; of Letters Patent No. 319,303, dated June 2,1885.

Application filed March 11, 1885. (N0 model.) Patented in France August5, 1884, No. 165,650.

To all whom it may concern.-

Be it known that LJEAN NoUGUEsFils ain, a citizen of the Republic ofFrance, residing at Ogen, in France, have invented new and usefulImprovements in or Relating to Canals and to the Navigation thereof, ofwhich the following is a specification.

The object of this invention is to do away with the necessity forhaulage and for towing in canals and canalized rivers by transformingtheir waters into reversible or returning currents into continuous ones,enabling boats to travel upstream or downstream without recourse to anyother motor but the natural feed of the canal. The application of thissystem to all canals and canalized rivers consists, first, inconstructing in each reach a dike or dam parallel to the axis of thecanal, the dike then forming two water-ways, one for going upstream, theother for going downstream. This dam stops short at somedistance fromthe sluice.

Figure 1 is a plan of acanal embodying this invention; Fig. 2,longitudinal section thereof Fig. 3, section on a b through one sluice;Fig. 4, a section through c (1 across the canal. Fig. 5 is a section online a f, showing one wall, side, or wing of a lock and the feed orsupply channel therein.

The like letters show like parts in all the figures.

A is a feed pipe or channel and causes motion of the water in the canal.B are the boats or the like; 0, the upper reach of the canal; G, thelower reach. D is the dike or dam. E, the tubular outfall or flume forthe upper sluice; E, a like connection for the lower sluice. F is thelock. G is the outfall into the stream corresponding in capacity withthe supply; It, the stream or river. For the motive power usuallyemployed for setting boats into motion currents are in this systemsubstituted which are produced by the difference of level in the variousreaches and by means of the tubular connections, channels, or flumesA,which are proportioned in accordance with the supply, and passingthrough one wing or side of the lock connect two reaches with oneanother. The channels A receive water from the reach O by the mouth E,and allow it to escape by the outfall E, this causing a fall or currentwhich, being repeated at each reach, causes movement of the waters inthe direction shown by the arrows; consequently the boats or vessels inthe canal move with the water in the direction of these artificialcurrents, which may be repeated or extended to any extent, and allowsvessels to be readily navigated in either direction and to be broughtback to the starting-point. The outfall G, which delivers into thestream R, must be of a capacity proportioned to that of the outfalls E,so that the same quantity of water flows into the stream as is suppliedby the channels A. Speed in this system is in direct proportion to thefeedthat is to say, the speed increases with the diameter of thechannels A.

I claim- A system of navigation for use in canals or canalized rivers,which consists of the various reaches thereof provided with the central1ongitudinal dikes, D, and the locks provided with feed tubes orchannels A, having outfalls E E at their ends, which arrangement has forits object the production of currents which carry the vessels or boatsand allow them to be navigated upstream or down, according to the sideof the dike at which they are placed.

In testimony whereof Ihave hereunto set my hand in the presence of twosubscribing witnesses.
